This aim is arrived at with the toy element according to the invention in that it comprises two or more spaced cup-like parts in which each of them comprises a portion extending from the bottom and having a small height, said portion fitting clampingly in the upper portion of a cup-like part of another element, said upper portion having a height which is a few times larger than the height of the shorter portion, both portions of greater height of the cup-like parts or of each two consecutive cup-like parts of the toy element being interconnected by at least one connecting part. In view of the fact that the exterior cross-sectional surface of the portion having the smallest height is substantially equal to the interior cross-sectional surface of the portion of the largest height, said portions having the smallest height can be inserted clampingly in a portion having the largest height of another toy element. The toy element according to the invention may be manufactured, in a manner known per se, from synthetic polymer material, for example polyvinyl chloride. Since each two toy elements can be interconnected in various positions, it is possible to form many different combinations with one and the same number of toy elements according to the invention. A child having a number of toy elements may supplement said number with any number of identical toy elements so that it is capable of building more complicated representations.

According to the invention both cup-like parts may be identical and the exterior cross-sectional surface of the portion having a small height may be substantially equal to the interior cross-sectional surface of the portion of larger height of each cup-like part.

A preferred embodiment of the toy element according to the invention is characterized in that the crosssection of each of the cup-like parts has the shape of an equilaterial polygon. Thus the composition of the required representations or structures is easier because the toy elements can assume a number of positions relative to each other corresponding with the number of sides of the polygon which at the maximum is equal to the number of sides of each toy element.

The toy element according to the invention is embodied such that the cross-section of each of the cup-like parts has the shape of an equilaterial polygon. Such a toy element offers the advantage that the elements are adapted to interlock with comparatively broad surfaces enabling the forming of sturdy spatial structures or compositions.

If necessary the cross-section of each of the cup-like parts may be circular.

In order to arrive at a satisfactory clamping of the toy elements. when the portions of small height of the toy element are inserted in the portions of larger height, the inner wall of each cup-like part may be provided with at least one projection in the form of a rib or raised portion extending over at least part of said inner wall. It is preferred that the inner wall of the sides of each of the cup-like parts is alternately provided with two ribs extendingv parallel to each other.

A sturdy toy element according to the invention is obtained if the two cup-like parts or each two consecutive cup-like parts are interconnected by two parallel sheet-like connecting members connecting two parallel sides of said cup-like parts at the angular points, said sheet-like connecting members having a width which is equal to the width of the sides of the polygonal crosssection of the cup-like parts. It is preferred that the lower ends of the two sheet-like connecting members being interconnected by a bottom, said bottom being likewise connected with the cup-like parts.

The invention will be further explained below with reference to the drawings showing by way of example some embodiments of the toy element according to the invention.

The drawings show in:

FIG. 1 a side view, partially in section of the toy element with two cup-like parts having a cross-section in the form of an equilateral octagon;

FIG. 2 a top plan view of the toy element shown in FIG. 1;

FIG. 3 diagrammatically a toy element having three cup-like parts, and

FIG. 4 diagrammatically a toy element the cup-like parts of which have a circular cross-section.

The toy element 1 shown in FIGS. 1 and 2 comprises two identical cup-like parts having an equilateral octagonal cross-section and consists preferably of a suitable synthetic material, for example polyvinyl chloride. Each cup has a portion 2 and a portion 4 respectively of greater height than the portions 3 and 5 respectively of said cup-like parts. The height of the portion 2 and 4 is in the embodiment shown in FIGS. 1 and 2 three times the height of the portions 3 and 5.

The interior cross-sectional surface of the portions 2 and 4 of the cup-like parts is substantially equal to the exterior cross-sectional surface of the portions 3 and 5 so that the portions 3 and 5 of a toy element can be inserted into the portions 2 and 4 of other toy elements. Since the cup-like parts may assume eight different positions relative to the cup-like part of another toy element into which they are inserted, it is possible to create very complicated three-dimensional structures therewith. As a result of the difference in size of crosssectional surfaces of the portions 2, 4 and 3, 5 there is formed at the transition of the portions 3 and 5 with the smallest cross-sectional surface in the portions 2 and 4 with the largest cross-sectional surface a stop shoulder 6 serving as a stop for the portions 2 and 4 of the cuplike parts having the largest cross-section.

The portions 2 and 4 of the cup-like parts are interconnected at two consecutive ribs of said portions 2 and 4 by two connecting walls 7, 8 and a bottom 9 so that there is a cup of rectangular cross-section between said two cup-like portions 2 and 4. The width of the connecting walls equals the width of the sides of the cup-like portions 2 and 4 so that in the space formed by each of the connecting walls and the adjoining sides of the cup-like portions 2 and 4 a corresponding portion of another toy element may fit.

As is apparent from FIG. 2 the inner walls of the cuplike portions 2 and 4 are provided alternately with two parallel ribs 10. As a result the cup-like portions 3 and 5 are firmly clamped in the cup-like portions 2 and 4 of a toy element situated underneath.

FIG. 3 shows diagrammatically a toy element having three cup-like parts l1, l2, l3 interconnected by two cup-like parts 14, having a rectangular crosssection, and FIG. 4 shows diagrammatically a toy element comprising two cup-like parts l6, l7 interconnected by a cup-like part with curved walls l8, 19.

It is obvious that the invention is not restricted to the embodiments described above by way of example and shown in the drawings, but that these may be constructed in many ways without departing from the scope of the invention. The cross-sections of the cuplike parts may have for example also the shape of an equilateral hexagon or some other polygon. Furthermore the sides of the portions 2 and 4 having the largest height need not be flat but from a distance from the top end down to the bottom end they may have any shape.
